Is there a easy way to find out failed cameras ?

Hello: I have some cameras,sometime one or two of them failed like lose connection or “WARNING:000: send **** cmd failed : I/O error”,then i can't control all of them，i need to find out which one is the problem by test all of them one by one，or shut down all of the cameras and turn on again. So is there a easy way to find out failed cameras ? or just [/size]ignore the failed cameras and control the rest then i could find out which one is the problem.[/color]

I'm only answering because no-one else did. There was a similar discussion in the multi-camera thread. I came up with this addition to multicam.lua. The lines can be copy&pasted right above the following in multicam.lua:
